java - onAdImpression() 未在 Admob 监听器中调用

Question

在横幅广告中 onAdImpression() 不再被调用。

 mAdview = findViewById(R.id.bannertest);
    mAdview.setAdListener(new AdListener() {
        @Override
        public void onAdClosed() {
            super.onAdClosed();
            Log.w(TAG, "onAdClosed: ");
        }

        @Override
        public void onAdFailedToLoad(int i) {
            super.onAdFailedToLoad(i);
            Log.w(TAG, "onAdFailedToLoad: ");

        }

        @Override
        public void onAdLeftApplication() {
            super.onAdLeftApplication();
            Log.w(TAG, "onAdLeftApplication: ");
        }

        @Override
        public void onAdOpened() {
            super.onAdOpened();
            Log.w(TAG, "onAdOpened: ");
        }

        @Override
        public void onAdLoaded() {
            super.onAdLoaded();
            Log.w(TAG, "onAdLoaded: ");
        }

        @Override
        public void onAdClicked() {
            super.onAdClicked();
            Log.w(TAG, "onAdClicked: ");
        }

        @Override
        public void onAdImpression() {
            super.onAdImpression();
            Log.w(TAG, "onAdImpression: ");
        }
    });
    mAdview.loadAd(new AdRequest.Builder().build());

有什么方法可以跟踪横幅广告的印象吗？

引用:https://developers.google.com/android/reference/com/google/android/gms/ads/mediation/MediationNativeListener#onAdImpression(com.google.android.gms.ads.mediation.MediationNativeAdapter)

public abstract void onAdImpression (MediationNativeAdapter adapter)

表示已为广告记录一次展示。此方法应仅 be called if setOverrideImpressionRecording(boolean) is set to true .这用于发布商指标，并且必须在任何其他事件之外调用。

An impression simply says that the ad is present so the onAdLoaded is where you would want to place your impression tracking.
